7. A carriage return or line feed imbedded in a quoted string does not terminate
the string, but is treated as just another character in the string.
8. The maximum length of a quoted string returned from a query is 1000
characters.
Here are some invalid strings:
H "Invalid string argument'
(quotes are not of the same type)
H "test<EOI>"
(termination character is embedded in the string)
Several digitizing oscilloscope commands use a block argument form:
Symbol Meaning
<NZDig>
A nonzero digit character, in the range 1–9
<Dig>
A digit character, in the range 0–9
<DChar>
A character with the hex equivalent of 00 through FF
hexadecimal (0 through 255 decimal)
<Block>
A block of data bytes, defined as:
<Block> ::=
{ #<NZDig><Dig>[<Dig>...][<DChar>...]
| #0[<DChar>...]<terminator> }
<NZDig>
specifies the number of
<Dig>
elements that follow. Taken together, the
<Dig>
elements form a decimal integer that specifies how many
<DChar>
elements follow.
Figure 2–2 provides a diagram of block argument use.
